BX 24 2WD

[megaboz]

Ok, so I always mow in 4wd, but I have a job where I can't go through their paved parking lot in 4wd, so obviously I use 2WD. Well one morning I forgot to put it back in 4WD, I slid down this embankment so fast, my tractor needed to change it's oil . It was a little steep, but nothing that severe.

Obviously I know better than to use 2wd, but if this thing is such a rocket when in 2wd, it is scary to think that the only thing that holds it back any other time is one of those little front tires!

Just wondered if anyoneelse ever had similar experiences with scaring your tractor.

Check with MissouriThunder as he had a similar "joyride" and did a thread on it.

As for me, I will have to get back with you on that one

I always mow in 2wd and rarely use 4wd unless I need the traction. Course I'm in a nice hilly valley and not mowing mountain cliffs in WV

In a related type of occurance, a poster from awhile ago on another forum had a harrowing experience with his BX2230 (or could have been a BX2350) running wild down a hill and even posted a video of a re-creation of it. Ends up he & Kubota recommended that he always traverse his many hills in 4wd and at a high throttle setting. He was alittle above idle in his video which he said he operated at when he wasn't working the BX, just in transporting.
Seems the braking efficency of the BX's HST is enhansed by higher operating pressures. In other words, the lower the rpm the lower the braking efficency, the higher the rpm the greater the braking efficency.

As said by many posters in the past, 2 wheel drive equals 2 wheel braking and 4 wheel drive equals 4 wheel braking.

The issue of engine RPM and HST drive efficiency and operations is not one I can comment on.

I know my little Home Depot John Deere Scotts POS has to be run full throttle or its HST drive overheats and does not work very well... but I'm sure that is far, far removed from how a real HST tractor works.

My tractor is gear drive with hydraulic shuttle so I can't provide any knowledge on a real HST tractor other than me operating one once.

Dave, Didnt he have the loader full of wood and no counter weight ?? Most believed he just lost traction on the rear wheels. I have some pretty steep hills on my property, not cliff like and have not had any problems. But I also have my loader and BH on all the time as dont use it as my mower.

Was just the mower attached?? FEL?? BH??

Just glad it ended well not like the occurance that Dave was refering too.

It is not far removed from how a BX works. A BX gets quite hot, and needs to be run near maximum rpm for adequate cooling. The POS (as you called it) is the same, except it has a smaller transmission and therefore less opportunity to cool by radiant means.

The following link is to an embarrassingly long post that explains some aspects of heat generation in a BX.

Well, I was not using any brakes (technically according to the manual it doesn't have abrake, it has a parking brake if I remember correctly), and when in 2wd, it is 1 wheel braking (when not locking the diff) and 4wd is only 2wd without locking the diff. I have had it on opposite wheels front and back before, it goes real fast that way! I have since learn to lock the diff in that area!

I don't mow with the FEL or BH, makes it way to dangerous in our wonderful hills.

I have been in 4wd and had the soil peel right off of the clay, now that is a fun ride down hill, made me wonder how I was going to stop at the bottom of the hill.

I just think it is odd how the lightest part of th tractor seems to provide the most traction, kinda scary when you think about it.:confused2:
